Give your AI a memory
— and hands.
Connect Claude, ChatGPT, or any MCP-compatible assistant to your saved tabs, notes, and to-dos. Your AI searches and summarizes what you have kept — and saves new finds straight in: ask it for sites and it drops them into a fresh space, jots notes, updates to-dos, even shares a space. All right from your chat.

Frequently asked questions
Is it really free?
Yes. The whole local dashboard is free forever, no account — unlimited tabs & collections, up to 3 spaces, every widget (calendar, pomodoro, to-dos, notes), search, and import/export. Pro adds cloud sync, unlimited spaces, nested sections, automatic backups, sharing, and AI.
Which browsers does it work on?
Any Chromium-based browser — Chrome, Edge, Brave, Arc, Whale, Vivaldi, and more. (Firefox and Safari use different extension stores and aren't supported yet.)
Can I share with someone who doesn't have Mos Tab?
Yes. Pro gives you a public, read-only link anyone can open in a browser — no install, and it stays live as you edit.
What happens to my data if I cancel Pro?
Everything stays. You keep your local dashboard and all your content; you just lose the Pro extras (sync, sharing, AI). Cancel or downgrade anytime.
What data leaves my device?
Nothing, unless you turn on sync. Mos Tab is local-first: your dashboard lives in your browser. Sync (Pro) stores it so your devices can share it — that's it.
How does sync work?
Edit anywhere; every device stays in sync automatically, with conflict-safe merging. You can leave it off and stay fully local.
What is the AI / MCP connection?
Connect Claude, ChatGPT, or any MCP-compatible AI to your own tabs, notes, and to-dos — search and summarize what you've saved, create new spaces, add notes and tasks, even publish a share link, right from your assistant. Pro.
Will this slow down my browser?
No. New tabs open instantly and everything runs locally. It's built keyboard-first to get out of your way.
